Huckleberry Finns usual place fro sleeping?

In Mark Twain's "The Adventures of Huckleberry Finn", Huck has two distinct lifestyles. One is on land, where he either resides with a conservative widow who wants to civilize him or with his drunken father. The second lifestyle is that on the raft where he travels with the escaped slave, Jim. While he is powerless on land, he is king of the world on the raft and doesn't have to live or operate within the confines of societal rules or pressures.
